This switches the interface of the runtime profiler to use frames as opposed to functions for performing on-stack replacement. Requests for such replacements need to target a specific frame. This will enable us to activate bytecode as well as baseline code for the same function. The existing %OptimizeOsr runtime function also had to adapted and now takes an optional stack depth to target a specific stack frame.
